You just might have corrupt cookies from this website. That will give you problems. Dump your cookies and try those programs I mentioned, they should work. If not, then I might agree with Paulette (not just yet though).
PS: Paulette, if the problem was coming from curezone, everyone would be having the same problems. But, there are just a few people complaining, not the majority of people. Beside, the mere fact that MH's browsers cascade indicate a problem with his machine and not the website.
